It's also the one that will have most effect, braking on my old steel winter bike, which has old cantilever brakes but thankfully alloy rims, went from pretty crappy to very good by fitting koolstop dual compounds vs the original tiny solid rubber blocks. The friction between block and rim is main factor in braking, the calipers etc just dictate how hard you have to pull to apply the correct force. At then end of the day the limiting factor is also the contact patch between tyre and road, which you can't do much about.

Best check your wheels if you are upgrading to 11-spd;if they are the same Giant ones as on mu better half's Liv Avail(women's version of the Defy)then they are not 11-spd compatible.
If 10-spd is ok I'd be tempted by the new Tiagra as a cheaper alternative.
As others have said though it's worthwhile trying the new pads option first.

You would need 5700 calipers 5800 are the one which have the different pull ratio

first off, an 11-speed cassette will not fit on your existing rear wheel so you will need a new rear wheel. Sora levers are compatible with 5600 calipers, but most like not 5700 and definitely not 5800. Although the brakes will 'work' they will not be at their best.
A 105 5800 groupset with a new rear wheel that is 11-speed ready is what you need. Did you know that a new 105 groupset is about to be launched so 5800 will possibly be reduced in price, however with the falling £ and Brexit I'd buy ASAP as prices are only going up very soon.

5600 5700 5800 all have different pull ratios

No you won't. You'll be okay with the rear wheel you have, dependant on whether the existing freehub body is long enough to take an 11 speed cassette, it could be that the existing freehub body is long enough for an 11 speed cassette, and that the 9 speed cassette is on there with spacers. It's not s big job to get an 11 speed compatible freehub body, if needs be, and cheaper than an unnecessary new wheelset. As has also been correctly stated, the pull to click ratio of the 11 speed set up will be different.

There seems to be so much conflicting and confusing information regarding what levers work with what brake calipers.
The chart at http://www.celebrazio.net/bicycling/shimano/2015_compatibility.html seems to show that the 3500 levers would work fine.
Anyway, I think I am just going to go for replacing my pads for the time being and see how that goes.
Thanks to everyone for your advice.

the chances of his rear wheel accepting an 11 speed cassette are close to zero. Putting an 11-speed freehub body on a 9/10 speed hub is not going to work either

the conflicting advice comes from 3 places:
1. the correct accurate advice
2. people who don't know what they are talking about but think they do
3. the definition of 'compatible' - some people says it's compatible if it works to an acceptable level (to them) whilst others (i.e. Shimano) only say it's compatible if it works perfectly and was designed to the same spec.

That's the best idea. Try it first, deal with it later, saves a lot of unnecessary buggering about and cost.

My experience says different.
My commuter has Sora, and originally had Tiagra calipers. The brakes were useless.
I did the often recommended first upgrade to Swisstop green pads. They were still useless.
Then I swapped to 5800 calipers - a massive improvement. More stopping power than I could ever need in the dry and okay/good in the wet - especially from the drops. I've not bothered to try the Swissstop pads yet - just using the ones that came with the calipers.
Don't bother with 5700 calipers. They're a completely different design and probably no better than what you have now.
